Slickgrid, column with a drop down select list?

Question

Hi I was wondering if anyone knows if it's possible to define a column in slickgrid as being a drop down select list. If not does anyone with some experience with slickgrid know how I should go about adding this option?

Thanks

You probably dont want to make a new select editor for each range of options. Also you may not know that range of all option value beforehand.

In that case you want a flexible range of options in a select type editor. In order to do this you can add an extra option to your column definitions (e.g. called options) like this:

 var columns = [
  {id:"color", name:"Color", field:"color",  options: "Red,Green,Blue,Black,White", editor: SelectCellEditor},
  {id:"lock", name:"Lock", field:"lock",  options: "Locked,Unlocked", editor: SelectCellEditor}
 ]

and access that using args.column.options in the init method of your own SelectEditor object like this:

 SelectCellEditor : function(args) {
        var $select;
        var defaultValue;
        var scope = this;

        this.init = function() {

            if(args.column.options){
              opt_values = args.column.options.split(',');
            }else{
              opt_values ="yes,no".split(',');
            }
            option_str = ""
            for( i in opt_values ){
              v = opt_values[i];
              option_str += "<OPTION value='"+v+"'>"+v+"</OPTION>";
            }
            $select = $("<SELECT tabIndex='0' class='editor-select'>"+ option_str +"</SELECT>");
            $select.appendTo(args.container);
            $select.focus();
        };

        this.destroy = function() {
            $select.remove();
        };

        this.focus = function() {
            $select.focus();
        };

        this.loadValue = function(item) {
            defaultValue = item[args.column.field];
            $select.val(defaultValue);
        };

        this.serializeValue = function() {
            if(args.column.options){
              return $select.val();
            }else{
              return ($select.val() == "yes");
            }
        };

        this.applyValue = function(item,state) {
            item[args.column.field] = state;
        };

        this.isValueChanged = function() {
            return ($select.val() != defaultValue);
        };

        this.validate = function() {
            return {
                valid: true,
                msg: null
            };
        };

        this.init();
    }
